Abstract

A light-emitting diode ( 1 ) is furnished with a semiconductor laminate ( 6 ), optically reflective layers ( 17 ) and ( 19 ), an optically reflective film ( 25 ), and a phosphorescent plate ( 27 ). The laminate ( 6 ) is formed by an n-type cladding layer ( 9 ), an active layer ( 11 ), a p-type cladding layer ( 13 ), and a p-type contact layer ( 15 ), laminated in order onto a substrate ( 7 ). The optically reflective layers ( 17 ) and ( 19 ) are provided respectively on the p-type contact layer ( 15 ) and on the back side ( 7 b) of the substrate ( 7 ). The optically reflective film ( 25 ) is provided on the three side surfaces of the laminate ( 6 ). The phosphorescent plate ( 27 ) is mounted on a side face among the side faces of the laminate ( 6 ), on which there is no optically reflective film ( 25 ). Blue light (L 1 ) outputted from the active layer ( 11 ) is reflected on each of the optically reflective layers, and is gathered on the side face on which the phosphorescent plate ( 27 ) is provided. A portion of the blue light (L 1) turns into yellow light (L 2) in the phosphorescent plate ( 27 ), and white light derived from the blue light (L 1) and yellow light (L 2 ) is emitted.
